"It is with a heavy heart that I share that my beloved soulmate, Christian Evans has passed," Lake wrote alongside a sweet image of herself and Evans. "The world didn’t understand this man, but I did."
"He succumbed to his life long struggle with bipolar disorder. For anyone who has ever lost a family member or friend to mental illness, my heart goes out to you," she continued. "I am a greater person for having known him and spent the past 6 and a half years of my life with him. He was a man of love and what mends my broken heart today is knowing that he is finally at peace and his spirit is free."
Lake and Evans, a jewelry designer, started dating in 2010, and married in 2012. The actress filed for divorce from Evans in October 2014. Though the pair put their divorce on hold two months later, they eventually decided to go through with their split, finalizing their divorce in 2015.
